ABSTRACT:
A manually powered pair of crank operated flat paddles used by a swimmer combines a rotary and paddling motion. One paddle is rotated to engage the water while the opposite paddle is disengaged and provides flotation only. The opposite paddle is then rotated to engage the water while the first paddle is disengaged. This apparatus combines support with propulsion to assist the beginning swimmer. The motion of the swimmer's arms using this device mimics a normal swimming stroke and aids the learning process.
